The yard felt honored of such an interest and immediately dedicated all of the energies available then and today to guarantee total satisfaction of the Owners-to-be. After their first meeting, the design was entrusted to Philippe Briand, at his eighteenth model for CNB. Following the demise of the Prince, the yard decided to continue the construction of the yacht he had so passionately ordered, this choice was taken by the yard's managers to honor the Prince's memory. Hamilton II underwent a few changes and today is a sailing reality of the chartering world. She is one of the most important projects carried out by the French yard after the initial record set with the construction of the 104' CNB Only Now. With Hamilton II, CNB set a new record by using the same vacuum infusion process with carbon, vinyl ester resin and balsa sandwich. Definitely she is a unique yacht in her genre, as all leisure yachts of this size. Even though she includes all sorts of comforts that may come in handy during long cruises she shines for her performance, in fact she is ideal for transatlantic crossings as well as regattas. Performance is the result of weight control obtained with vacuum infusion using light and resistant materials such as carbon, a lifting keel with a 30-ton bulb feature which enables her to have a displacement of less than 100 tons and a sail area of 570 square meters. Sail area and hull guarantee extreme safety in any sea and weather conditions for Hamilton II was conceived to sail anywhere in the world and all year round. Andrew Winch Designs and Philippe Briand, respectively in charge of interior styling and outside design, had to solve several technical problems during the design development for the Owner requests included comfortable habitability and high performance against reduced draft. To keep the original weight values, designers resorted to different solutions, some of which used in aeronautics. Such solutions enable to fit all sorts of accessories for comfortable living without affecting weight thus guaranteeing excellent performance even when sailing in a light breeze.

Hamilton II represents one of the most recent examples of cruisers-racers, boats whose main feature is to offer comfortable and cozy cruising over long periods of time combined with high performance. Just like other models built according to this philosophy, no compromise was reached. Rather, the yacht was designed on the basis of research studies carried out in different fields. The materials used, for example, are the same as those used in the aeronautical field; they allow considerable weight reduction and suitable weight distribution guaranteeing excellent seakeeping ability. Even the deck represents the double nature of this yacht. Even though the trunk is fitted amidships, its profile is low and there are ample side decks. The stern includes two steering wheels from where one can easily check the sail area under any point of sailing. As far as interiors are concerned, there is an ample, full beam stateroom aft, with two en suite bathrooms, two beds and a corner desk. Going forward there is another cabin to port, with single bed and en suite bathroom. The midship section of the yacht includes the comfortable dinette to starboard and the saloon to port, both with natural lighting and headroom thanks to the overhead trunk. Forward of this area there are two mirror cabins with twin bed and en suite bathroom. Forward, in the bow, there are the galley and the crew quarters with the crew dinette, a double cabin for the captain with en suite bathroom and desk and two cabins with Pullman bunks and bathroom. The yacht is fitted with two dinghies, an 80hp engine Zodiac Projet stored in the aft garage and a smaller Zodiac pram stored forward on deck. Useless to say that onboard Hamilton II there are several high-tech audio-visual systems and the most modern electronic navigation equipment. Even the imposing sail area is controlled by automatic systems that considerably reduce the number of crewmembers and above all offer pleasant sailing as well as excellent performance under sail and under engine power. The engine is a 430 hp 6R183 TE82 MTU, the sloop is fitted with a 9/10 rig, Hall Spars 42.25 m high carbon mast with four sets of spreaders, carbon boom and total sail area with mainsail and genoa of approximately 571 sq. m. Lewmar deck fittings include eight hydraulically-operated winches and two Cariboni Magic Trim for the mainsail. Even sails meet the high-tech standards found onboard Hamilton II, in fact, mainsail, solent jib and staysail are D4 Vectram/Carbon sails, in addition there are a Dacron storm jib, an Airx 900 asymmetrical spinnaker and a spinnaker inside its chute stored below deck. This yacht undoubtedly offers high performance sailing in any wind conditions nevertheless she also features a classic design and very cozy and ample interiors.
